To all whom it. may concern:

Be it known that I, WILLIAM E. SHARP, a citizen of the United States, residing at Chicago, 1n the county ofCool: and State of Illi- 1101s, have invented certain new and useful Improvements in Angle-(lock Supports and Looks for Air-Brake Systems, of which the following is a specification.

This invention relates to the general art of air-brakes for railway cars, and has reference more particularly to a new and improved device for supporting and locking the usual angle-cock which couples the train-pipe to the brake-hose in a fixed position. The

Master Car Builders standards for the application of air-brake pipes to freight cars require: (1) that the center line of the drainpipe shall be a specified distance from the scenter line of the coupler of the car; (2) that the transverse center line of the angle-coek shall be a specified distance from the face of the coupler; and (3) that the angle-cock shall be set at a specified angle from a perpendicular line, so as to prevent kinking. of

the brake-hose when they are coupled up. Itis important that the train-pipe be not only made to meet these conditions, but that it be securely attached to the car in a manner to prevent its shifting and breaking the couplings when cars are being switched. A

broken or leaky air-brake pipe is a serious defect in railway operation, and is usually the result of a ipe shifting when the cars are bumped n fact, the majority of the trainline failures are due to this defect, which re sults from the pipes not being securely fastened to the car.

* To avoid the faults hereinabove specified, and to provide a device wherein the specified angularity of the angle-cock shall always be maintained, constitute the chief objects of the present invention, which are attained in a device embodying the constructional characteristics and features of that shown in the 4 accompanying drawings, in which,

Figure 1 is a side elevational view of my improved device, partly in vertical section, showing the manner in which the same is attached to the end sill of a car. Fig. 2 is a view partly in front elevation and partly in vertical section on the line 2-2 of 1.

Fig. 3 is a perspective view of the train-pipe bracket, detached with the locking key withdrawn.

'. 5 1 IR eferring to the drawing, 5 designates the end channel or any other form of end sill of a ear, to which is rigidly attached, as by screwtangular apertures 14 and 15, respectively,

which are adapted for the reception of a looking key 16. The forward end of this latter is undercutor notched, as shown, thus forming a locking projection 16 that is adapted to overlie one of the sides of the polygonal coupling member 17 of the usual angle-cock designated as an entirety by 18, and a shoulder 16* that is designed to abut against the contiguous face of said coupling member; the locking key being confined in looking position by a nut 19 on the threaded end of the train-pipe 13; said nut screwing up hard against the face of the flange 12 of the bracket and, in such osition, abutting against the rear end of te locking key, as clearly shown in Fig. 1, confining said key against endwise movement between said nut and said coupling member. In this osition the projection 16 of the hey, overlying and contacting with one of the polygonal faces of the coupling member, locns said coupling member against turning in either direction, and this maintainsthe angle-cock in its fixed and correct position.

The supporting bracket, constructed as shown and described, is comparatively light, and yet affords a perfectly rigid support for i the end of the train-pipe and the ang e-cock,

and possesses a high degree of strength to resist lateral strains occurring in a direction either longitudinally of or transverse to the train-pipe. The device does not interfere with the ready application or uncoupling of the angle-cock; since for this it is necessary only to back on thenut 19 and retract the locking-key sufficiently to withdraw its nose 1 16 from. over the coupling member 17, as indicated in dotted lines in Fig. 1. It may also be noted that the locking key 'not only maintains the angle-cock in iiued angular position, but it also constitutes in efiect a nut look preventing any accidental unscrewing or uncouplingof the angle-cock, thus insuring its operative oonneotlon with the train-pipe when in service. I

I claim:

1. An angle-cock support and train pipe connection comprising a bracket adapted to be secured to and depend from the end sill of a car and having an aperture for the pas sageof the .train pipe, 'in combination with a train pipe having a threaded end passing through said aperture, an angle-cock having a. threaded connection with said end and bearing against the front of said bracket, and a locking nut threaded on the train pipe and bearing against the opposite side of said bracket, substantially as described.

- 2. A support for the end of a train-pipe,

comprising a bracket having at its upperend attachment-plates adapted tobe secured to the frontand under side of the end sill ofva ear, and a dependinglportion having formed in its lower end a cy 'ndrical bearlng' for the end of the train-pipe.

3. A support for the end of a train-pipe, comprising a bracket having at its upper end attachment-plates adapted to be secured to the front andiunder side of the end sill of a car, a dependin fiat body-portion having reiniorcin ribs 'sposed in a plane at right angles t ereto, and a cylindrical bearing for the end of the train-pipe at the lower end of said body-portion.

. angle-cock lock, comprising a brac sill of a car and having a bearing for the end of a train-pi a locking key mounted in said bracketan adapted to engage and lock the angle-cock coupllng in position on the end of said train-pipe, and means for remoyably confining said locking key in operative position;

6. A combined train-pipe support and angle-cook lock, comprising a bra'c et adapted to be secured to and depend from the end sillof a car, said bracket having a bearing formed therein for the end of a train-pipe and, to one side of said bearing, an aperture,

-a locking key slidably mounted in said a erture and having a forwardend adapte to piojeet over one side of the olygonal coupg member of an angle-coo and a nut on the train-pipe adapted to engage the rear end of-said locking key and malntain thelatter in operative. position.
